This program was developed for those who wish to convert their save files offline, rather than having to go to the online one.
It uses a similer inteface, and supports conversion between the following save types:

System Requirements:
-.Net Framwork 2.0 or 4.0
-Windows (Vista or 7 prefered, XP may or may not work)

Change log (2.6 Alpha):
I am very hesitant to release this just yet due to lack of testing, but converting was somehow broken in v2.5, and I just had to release something. The conversion is fixed, and plugins are now updated. This is no longer the "NDS Save Converter", but the "Generic Save Converter that happens to have NDS formats built in". (Maybe I should just stick with the old name?) ANyway. Plugins no longer go in the /Plugins folder, but in the /Plugins/Format folder. Example, included is a GBA plugin in /Plugins/GBA. Developers can put plugins into folders like this, so they can use the converter to convert ANY kind of save file that has a raw format that comes in powers of two (256KB, 512KB, etc) and with a size less than 128MB.
